What solutions are people using for transmitting on HF bands (1 - 30 MHz)?
There is a lot of information online about upconverters for receiving the HF bands. However, like receivers, many of the SDR transmitters only seem to cover bands above 30MHz[1] e.g. HackRF: 30MHz - ... bladeRF : 300MHz - ... USRP B2x0: 50MHz - ... Is anybody using a downconverter or is there some other SDR model that natively supports the HF spectrum and is accessible to hobbyists? Some other things come to mind: - power amps for HF bands - RF switches for using a single antenna in half-duplex mode, alternating between receive and transmit 1. http://www.taylorkillian.com/2013/08/sdr-showdown-hackrf-vs-bladerf-vs-usrp.html _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
